How does random shuffling of an array

Question

I need to randomly shuffle the following Array:

int[] solArr = {1, 2, 3, 4, 5, 6, 6, 5, 4, 3, 2, 1};

Is there any function to do that?

Answer 1

simplest code to shuffle:

import java.util.*;
public class ch {
    public static void main(String args[])
    {
        Scanner sc=new Scanner(System.in);
        ArrayList<Integer> l=new ArrayList<Integer>(10);
        for(int i=0;i<10;i++)
            l.add(sc.nextInt());
        Collections.shuffle(l);
        for(int j=0;j<10;j++)
            System.out.println(l.get(j));       
    }
}

Answer 2

Here is a simple way using an ArrayList:

List<Integer> solution = new ArrayList<>();
for (int i = 1; i <= 6; i++) {
    solution.add(i);
}
Collections.shuffle(solution);
